Abstract

The invention proposes a multi-control type air exhausting device and method for a greenhouse, and the device comprises a power supply, a power conversion module, a wireless data transmission module, an identity verification module, a central processing unit (CPU), a relay control module, an AC contactor control module, and an exhaust fan. The method comprises the steps: setting the upper limit value and a lower limit value of internal gas parameter values of the greenhouse, detecting the internal gas parameters of the greenhouse, comparing the detected gas parameter values with the upper and lower limit values, and controlling the air exhausting device according to the comparison result. The device and method can be remotely controlled and commanded, can achieve multiple purposes, and saves more cost.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a multi-control ventilation device and ventilation method in a greenhouse. Background technique [0002] The space in the greenhouse is small, and the shed is relatively sheltered from the wind, coupled with the use of pesticides and the effect of fertilizers, the carbon dioxide content in the greenhouse continues to decrease, and more and more harmful gases accumulate, causing crop diseases in the shed. It will have adverse effects on the growth and development of crops in the greenhouse. Therefore, when the air component content in the greenhouse does not meet the growth requirements of the crops in the greenhouse, ventilation treatment must be carried out to remove the dirty air in the greenhouse. At the same time, the The fresh air outside the shed is displaced in. [0003] For most farmers, they still use the traditional method to exhaust the air, that is, when the air is needed,...
